I have some Custom Post Types with ACFs. In a csv I have all the data. I want the data imported and show as Custom Post Types and mapped to the ACFs. Is there a import tool (if yes which? is it a free tool?) to do that or do I need to write my own php function which does that (any hint how to do that)?
The best solution I’ve ever found is using WP All Import. They even have an ACF plugin to make it easier. You basically upload your file and map the fields.
Whilst not free, it’s well worth the investment!
@jarvis is correct about using WP All Import. But it is still a one time purchase. Buy it once and use it forever.
Building something yourself is not easy, to say the least.
